  • Some randomization and hysteresis to the network selection decision may be used, as discussed in 3GPP R2-131348, which is hereby incorporated herein by reference in its entirety. This randomization and/or hysteresis may limit simultaneous WLAN offload initiation/termination of a large number of UEs and ping-pong effect between WLAN-3GPP
  • Certain embodiments may have various benefits and/or advantages. For example, certain embodiments may allow flexible and optimal offloading and on-loading decisions, with respect to 3GPP and WLAN networks, for UEs in idle mode accounting for system dynamics, such as dynamic behavior of 3GPP and WLAN networks including target QoS and load/congestion conditions. Thus, for instance, a UE may move back to 3GPP if WLAN access results in degraded QoS/QoE due to, for example, congestion. Furthermore, a UE may attempt to start data transmission immediately in the network (e.g. WLAN or 3GPP) which may provide better QoS, without establishing for example an R C connection first to a 3GPP network before being redirected towards WLAN due to, for example, high load. Thus, certain embodiments may reduce signaling overhead and extra latency.

Abstract

Divers systèmes de communication, tels que des systèmes de communication sans fil, peuvent profiter de techniques d'équilibrage de charge. Par exemple, une sélection d'un équipement d'utilisateur basée sur la qualité de service/charge entre un réseau local sans fil et un réseau cellulaire au cours d'un mode inactif peut être bénéfique à un grand nombre de systèmes de communication. Un procédé peut consister à recevoir, par un équipement d'utilisateur, un ou plusieurs seuils de qualité de service, seuils basés sur la charge du système, seuils basés sur l'intensité du signal ou la qualité du signal correspondant à un ou plusieurs critères pour une technologie d'accès radio. Le procédé peut également consister à sélectionner, par l'équipement d'utilisateur, une technologie d'accès radio parmi une pluralité de technologies d'accès radio pendant que l'équipement d'utilisateur est, par exemple, en mode inactif, sur la base du ou des seuils en combinaison avec les critères correspondants.
